Same question here. Does it need to be permanently fixed in place? I know next to nothing about the SBR rules.

Guys,
Take your fake can screw it on your rifle till it bottoms out on the SB. Mark dead center on the bottom remove the fake can drill and tap about 3/8" to 1/2" in from the end on the center line for a #10-24 1" long S.S. allen head screw. take the screw and grind it to a slight point 10-15 degree (careful not to ruin the threads) put your fake can back on install the screw w/locktite tighten and cut off smooth finish to match and it is blind pinned. removing the fake can will now destroy the threads but it can be removed to SBR if you change your mind by drilling the screw and using an easy out . HTH Just my opinion Artty

thanks Artty62 ive been trying to figure out how to do it, i was thinking you just drilled a hole through your fsb threads and stuck a pin in there and smashed it down kinda like a gas piston rivit.

im not real sure if drilling a hole in my FSB threads on a krink is really worth it or not, im kinda leaning towards no its not lol

If I'm not mistaken I believe you still need to weld the top of the blind pin.

Other options - if the can is steel you can spot weld four places, or use high temp silver solder from brownells apply paste to threads and then heat the can til glowing red.

the BATFE has ruled that there are 2 ways to pin, one is SILVER solder and the other is to weld over the pin. No locktite is considered permanent by the BATFE

Your theories are sound but try welding or silver soldering on the aluminum fake cans. The method I describe is one way to try and comply and as I said it was my "opinion" not the law. Artty

I'd like to see someone try to remove it, I don't think it would go anywhere.

Youre right about the aluminum and silver solder, thanks arty, but depending on which aluminum is used it may be tig able. If not, and you are going to use the loctite method put it on the bbl threads too.

Unfortunately common sense and ATF regulations rarely go hand in hand. :neutral:

Ok, you can go to jail

Try to comply does not fly with the ATF

Then use an aluminum blind pin and weld it

" if the can is steel ..."

As I said before the blind pin police jumped my ass. I was offering my "OPINION" and not Fact or Law nor did I tell anyone to jump right to it and break the Law. Artty

I just responded to "but try welding or silver soldering on the aluminum fake cans" when I said IF THE CAN IS STEEL. Seemed like you got defensive about me ADDING information to your post about a serious legal matter.

No bad blood man but don't insinuate to other people that they don't know basic welding 101 and then jump up and say just my OPINION

Yes, use an aluminum blind pin and weld it in place. This seems to be the only atf approved method, Anything not silver soldered or blind pinned/welded would be illegal.

sweet thanks, so basically i would take an aluminium rod, stuff it down the drilled hole, grind it down a bit, weld it (tig weld i would assume) then grind it down to look smooth?

you can by aluminum brazing rod it will work to weld over a pin. You could use a steel pin as well. It has to be welded over not welded to the pin. The aluminum brazing rod will give you a nice weld to aluminum and is very easy. with minimal practice you can weld 2 pop cans together
